Following this method, we infer that the DLA host galaxy is
forming stars at \(\dot{M}_{\rm SF} \approx 21 M_\odot \)  yr\(^{-1}\) 
for an average \(f_{esc}\approx 9\%\)  and
\(f_{esc}^{Ly{\alpha }}\approx 5\%\) . However, this value is highly
uncertain and ranges between \(2 \le \dot{M}_{\rm SF} \le 53\) 
[M\(_\odot \)  yr\(^{-1}\) ] if we account for the large uncertainty in
the Ly\(\alpha \)  escape fraction from 70% to 2%, respectively
[1]}. A similar SFR
of \(\sim 2 M_\odot \)  yr\(^{-1}\)  is also inferred from the star
formation rate calibration for \(H\alpha \)  luminosity [i.e.
\(L_{H\alpha }\) [erg/s] = 10\(^{41.27}\)  * SFR \(M_\odot \)  yr\(^{-1}\) ] from
[2]} and the intrinsic
\(Ly\alpha /H\alpha \)  ratio of 8-10. This is comparable with the
typical SFR of Lyman break galaxies at the similar redshifts
[3]}.
